Nrf52840 preview dk not getting detected

[nileshpassi]

I have brought nrf52840 preview dk ,it is not getting detected by the computer nor its power led getting light up. Last code i  tested  on its was blinky.

I doubt it has any hardware issue as i have not interfaced any device  with the dk.

I have also checked the test point  around switching circuit on dk it was ok.

Put nRF power source switch in the VDD position. Make sure that SW6 is in DEFAULT position and SW10 is set to ON.

Try to replace the USB cable. And make sure it's connected to J2 not "nRF USB"

I would recommend getting a newer version of the DK. The preview DK has an early engineering version of the chip which has lots of issues.

I have done the setting as you have but nothing change, why is the led 5 is not getting light up and why it is not getting detected by the computer,can you help on the test point , so that i can verify whether it is getting  the correct voltage at correct point if it is then it has to be a software issue.
